With Auto Sync on, ConnectBooks sends each settlement to QuickBooks Online by itself, once it's ready. You don't need to click Export.
Turn it on
Go to Accounting Export.
Pick a store. (Auto Sync is set per store, because each store can use a different QuickBooks company.)
Click More, then turn on Auto Sync.
Turn it on only after you're happy with how your exports look in QuickBooks.
What gets sent
A settlement has 2 parts: the Settlement (sales and fees) and, for some stores, the COGS (product costs). Each part goes out on its own when it's ready.
If products aren't mapped yet, the Settlement part waits.
If products are missing a cost, only the COGS part waits. The Settlement part still goes out.
Fix the warning on the Accounting Export page, and the waiting part goes out on the next sync.
Frequently asked questions
I use QuickBooks Desktop. Does this work?
Yes. With Desktop, Auto Sync gets the settlements ready, and they go into QuickBooks the next time the Web Connector runs.
Why didn't a settlement go out?
It probably has a warning, like unmapped products or a missing cost. Open Accounting Export and click the warning to fix it.
Can I turn it on for all stores at once?
No. Turn it on for each store.
